Final answer:
Adriana's walking rate is 1 block per 4 minutes and 4 minutes per block. She can walk around 11 blocks in 45 minutes using her rate of blocks per minute. This concept is related to equivalent ratios.
Step-by-step explanation:
3a. Adriana walks 5 blocks in 20 minutes. So the equivalent ratios would be shown as follows:
- 1 block = 20/5 = 4 minutes
- 2 blocks = 2*4 = 8 minutes
- 3 blocks = 3*4 = 12 minutes
- 4 blocks = 4*4 = 16 minutes
- 5 blocks = 5*4 = 20 minutes
Therefore, Adriana's rates are 1 block per 4 minutes and 4 minutes per block.
b. The rate at which Adriana walks is 1 block per 4 minutes (0.25 blocks/minute) and 4 minutes per block.
c. To know how many blocks Adriana can walk in 45 minutes, she can use the rate of blocks per minute. Let's calculate it:
Number of blocks = Total time / Time taken per block = 45/4 = 11.25 blocks
She can walk approximately 11 blocks in 45 minutes, since she can't walk a partial block.
